Mazda AZ-1: A Comprehensive Buyer's Guide

The Mazda AZ-1 (Autozam AZ-1 in Japan) is a mid-engined sports car produced by Mazda under its Autozam brand from October 1992 to October 1994. A product of the Japanese kei car (軽自動車) regulations, it's a unique and highly sought-after example of micro-sports car engineering. Conceived during Japan's economic boom of the late 1980s and early 1990s, the AZ-1 showcases innovative design and engineering within the strict kei car size and power limitations. It occupies a unique niche, offering exotic supercar styling and handling characteristics in a remarkably compact and affordable package. Its most distinctive feature is its gullwing doors, a rarity even among high-end sports cars.

Generations

The AZ-1 had a very short production run and therefore, did not go through multiple generations. However, there are notable variations and special editions to consider:

  • 1992-1994 (Initial Production): The original AZ-1, produced under the Autozam brand. It featured the Suzuki F6A engine and distinct gullwing doors.
  • Suzuki Cara (1993-1995): A badge-engineered version of the AZ-1 produced by Suzuki. It is mechanically identical to the AZ-1, sharing the same engine, chassis, and suspension. The only difference lies in the badging and minor trim details. It was sold for slightly longer than the Autozam AZ-1.
  • M2 1015 (Unofficial): While not an official "generation," the M2 1015 was a proposed, more hardcore version of the AZ-1 by Mazda's M2 tuning division. It never made it to full production but influenced aftermarket modifications and inspired enthusiasts. It featured a more aggressive body kit, Recaro seats, and other performance enhancements. A few prototypes were made, and their influence can be seen in later aftermarket upgrades.

Reliability & Common Issues

Despite its small size and limited production run, the AZ-1 is generally considered reliable, but its age and rarity mean careful inspection is crucial. Here's a detailed look at common problem areas:

Engine (Suzuki F6A)

The Suzuki F6A turbocharged engine is generally robust, but age-related issues are common:

  • Turbocharger: Inspect the turbocharger for excessive oil leaks, whine, or boost issues. Rebuilding or replacing the turbo is a common maintenance item. Ensure proper boost pressure is being achieved.
  • Oil Leaks: Check for oil leaks around the valve cover gasket, oil pan, and crankshaft seals. Regular oil changes are critical for turbocharger longevity.
  • Cooling System: Overheating can be a significant concern, especially in hotter climates. Inspect the radiator, hoses, and thermostat for leaks or corrosion. Consider upgrading to an aluminum radiator for improved cooling efficiency. Pay close attention to the condition of the water pump.
  • Timing Belt: The F6A uses a timing belt that requires replacement at specified intervals (typically every 50,000-60,000 km). Failure to replace the timing belt can lead to catastrophic engine damage.
  • Vacuum Leaks: Due to age, vacuum lines can crack and leak, leading to poor performance and idling issues. Thoroughly inspect and replace any suspect lines.

Drivetrain

  • Gearbox: The 5-speed manual gearbox is generally reliable, but check for smooth shifting between all gears. Listen for grinding noises, especially when shifting into 2nd and 3rd gear. Synchro wear is common with age.
  • Clutch: Inspect the clutch for slippage, especially under hard acceleration. Replacement is a straightforward but potentially costly repair.
  • Driveshafts: Check the driveshaft boots for tears and grease leakage. Listen for clicking noises during turning, which can indicate worn CV joints.

Chassis & Suspension

  • Rust: Rust is a major concern, especially in areas with harsh winters or salty roads. Pay close attention to the chassis rails, floor pans, and suspension components. Thoroughly inspect the car for any signs of rust repair.
  • Suspension Bushings: The original suspension bushings are likely worn out, affecting handling and ride quality. Consider replacing them with polyurethane bushings for improved performance.
  • Brakes: Check the brake rotors, pads, and calipers for wear and tear. Ensure the brake lines are in good condition. Inspect the master cylinder for leaks.
  • Gullwing Doors: The gullwing door hinges and struts are complex and can wear out over time. Check the hinges for play and the struts for proper support. Replacements can be difficult to source and expensive. Ensure the doors latch securely.

Electrical System

  • Wiring: Due to age, the wiring harness can become brittle and prone to cracking. Check for any signs of exposed wires or corrosion.
  • Electronics: Ensure all electrical components are functioning correctly, including the lights, wipers, and gauges. The original stereo may be unreliable.

Driving Experience

The Mazda AZ-1 offers a unique and engaging driving experience that few cars can match. Here's a breakdown of its characteristics:

Pros:

  • Handling: The mid-engine layout provides excellent balance and agility. The AZ-1 is known for its sharp handling and responsiveness, making it a joy to drive on twisty roads.
  • Lightweight: Weighing in at only around 720 kg (1587 lbs), the AZ-1 feels incredibly nimble and quick.
  • Unique Style: The gullwing doors and distinctive styling make the AZ-1 a head-turner wherever it goes.
  • Affordable Fun: Compared to other mid-engine sports cars, the AZ-1 offers exceptional value for money.
  • Kei Car Benefits: In Japan, owning a kei car results in lower taxes and insurance costs.

Cons:

  • Limited Power: The F6A engine produces only 63 bhp (47 kW), which can feel underpowered on the open road.
  • Tight Interior: The interior is cramped, especially for taller drivers. Legroom and headroom are limited.
  • Road Noise: The AZ-1 is not well-insulated, resulting in significant road noise and engine noise.
  • Ride Quality: The suspension is firm, providing a sporty feel but a less comfortable ride on rough roads.
  • Parts Availability: Parts can be difficult and expensive to source, especially for certain specific components.

Buying Advice

Purchasing a Mazda AZ-1 requires careful consideration due to its age and rarity. Here's some essential buying advice:

  • Condition is Key: Prioritize a well-maintained example with minimal rust. A mechanically sound car is more important than cosmetic perfection.
  • Rust Inspection: Thoroughly inspect the car for rust, especially in the chassis rails, floor pans, and suspension components. Use a magnet to check for filler.
  • Maintenance History: Look for a car with detailed maintenance records, demonstrating regular servicing and repairs.
  • Test Drive: Take the car for a thorough test drive to assess the engine, gearbox, suspension, and brakes. Pay attention to any unusual noises or vibrations.
  • Door Operation: Ensure the gullwing doors open and close smoothly and latch securely. Check the condition of the hinges and struts.
  • Parts Availability: Research the availability of spare parts before committing to a purchase. Join online forums and communities to connect with other AZ-1 owners.
  • Professional Inspection: Consider having a professional mechanic with experience in Japanese cars inspect the car before you buy it.
  • Pricing: Prices vary depending on condition, mileage, and modifications. Research current market values to ensure you're paying a fair price. The Suzuki Cara generally sells for less due to lower demand, despite being mechanically identical.
  • Years to Look For: All years are generally similar, but later production models (1994) might have benefitted from minor refinements.
  • Years to Avoid: There are no specific "years to avoid." The overall condition is more important than the year of manufacture.

The Mazda AZ-1 is a unique and rewarding car to own, offering a thrilling driving experience and head-turning style. With careful research and inspection, you can find a well-maintained example that will provide years of enjoyment.
